IMPROVEMENT IN ELEVATORS.

Specification forming part of Letters Patent No. 160,183, dated February23, 1875; application filed February 3, 1875.

T 0 all whom. it may concern:

Be it known that 1, CHARLES H. GUILES, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Dumb-VVaiters or Elevators, of which improvements the following is afull, clear, and exact description, which will enable others skilledinthe art to which my invention appertains to make and use the saidimprovements, reference being had to the accompanying drawing forming apart hereof, and in which Figure 1 is a front elevation of my improvedwaiter, and Fig. 2 a side elevation of the same.

Like letters of reference indicate like parts.

My object is to improve the construction and operation of that class ofdumb-waiters or elevators operated by hand and employed to convey smallparcels or packages from one story of a building to another, or from oneroom to another; and my invention consists in certain novel features,substantially as hereinafter described, relating to the means employedfor the purpose of accomplishing the objects above set forth.

In the drawing, A represents the lower receiving-box. This box may bearranged in the lower story of the building. Aand A are slides or doors,opening into the box A. B represents the second story of the building,and (J the third. D is a tubular way, entering the box A, andterminating in the upper story. E is an opening in one side of the wayD. This opening is arranged in the second story, as shown. F is atilting table or door, arranged in the opening E. One of the trunnionsof this door. is provided with a weighted lever or arm, a, by means ofwhich the door is held in a position to close the opening. In theexample shown, this door is in a vertical position when closed, thusleaving the way D unobstructed, and the arm a is weighted by means of acall'bell, a, attached thereto. Gis a cord attached to the arm a, andextending into the upper story. H is a receiving-box, arranged in thesecond story. I is a door, entering the way D from the second story. Jis shaft, arranged in the lower part of the box A. K is a ratchet-wheel,rigidly mounted on the shaft J. L is a wheel or disk, loosely mounted onthe shaft J, and provided with a crank-pin or handle, 0. This wheel ordisk is also provided with a pawl, 0, arranged to engage the teeth ofthe ratchet K, and held to its engagement therewith by means of aspring, 0. M and N are pulleys, rigidly attached to the shaft J. O is acord, attached to and wound upon the pulley N, and passing over in theupper part of the building. as shown. I? is a weight on the end of thecord 0. Q, is a bucket, arranged in the way D. It is a cord, attached tothe lower end of the bucket and to the pulley M, being wound on thelatter in a different direction from which the cord 0 is wound upon thepulley N. S is a cord, attached to the upper end of the bucket. T is ashaft in the upper part of the building. B and G are pulleys, rigidlymounted on the shaft T. D is a ratchet, rigidly attached to the shaft T.E is a pivoted stop-pawl, arranged to engage the ratchet D. F is a cord,attached to the heel of the pawl E, and extending to the lower part ofthe building. G is a crank on the shaft T. The cord S is attached to andwound upon the pulley B. H is a cord, attached to and wound upon thepulley G, being wound on the latter in a different direction from whichthe cord S is wound upon the pulley B. I is a weight upon the end of thecord H. J is a downwardly-yielding leaf, hinged to the wall of the upperstory, and K is a spring holding this leaf in a horizontal position. L"is a call-bell, attached to the leaf J. The cord S passes through anopening or hole in the leaf J, and is knotted above the said opening.The weight I is sufficient to keep the empty bucket at the upper end ofthe way D, which is open at the top, as is also the bucket. The ratchetupon the shaft J prevents the latter from being turned, except in onedirection, by means of the handle 0. The weight P causes the cord S tobe wound upon the pulley M when the bucket descends. The pawl E holdsthe bucket in any desired position.

When the bucket is at the upper story, and it is desired to send aparcel or package from the lower story to the upper one, the handle 0 isturned in the direction indicated by the arrow. This causes the descentof the bucket, the pawl E being released as soon as the downwardmovement of the bucket begins. By the the time the bucket reaches thelower story the knot in the cord S strikes the leaf J and sounds thebell L. The cord F is then drawn downward, thus throwing the pawl E intoengagement with its ratchet, and preventing the ascent of the bucketuntil the proper time. When the bucket is loaded the attendant, calledby the bell L, releases the pawl E from its ratchet, and causes thebucket to ascend by turning the crank G in the direct-ion indicated bythe arrow there shown. The bucket may also be sent from the upper to thelower floor by turning the crank G in the opposite direction, andsetting the pawl E when the bucket reaches its destination. The bucket,by striking the floor of the box A, will attract the attention of thoseengaged on the lower floor. When the bucket is filled a slight pull onthe cord S will indicate that fact to the attendant on the upper floor,by sounding the bell L, and the bucket may then be made to ascend in themanner described. The bucket may also be made to stop at the door I, andit may be sent from thence in either direction, either by grasping thecord S for that purpose, or in the mannerdescribed. A parcel or packagemay also be delivered from the upper to the next lower floor by drawingupward on the cord Gr, thus throwing the door F across the way D, atsuch an inclination as to conduct the parcel or package into the box H,it being understood that the parcel, in this case, is dropped into theupper end of the way D.

from one room to another on the same floor.

This result may be accomplished by arranging the parts, with theexception of the weights and bell L, in a horizontal position; and inthe-latter case the door F will be inoperative for the purposespecified.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent. is

1. The combination of the bucket Q, the cord R, the counter-weightedcrank-shaft J, the cord S, the counter-weighted crank-shaft T, theratchet-wheel D, pawl E, and cord F, all arranged and operating togethersubstantially as and for the purposes specified.

2. The combination of the bucket-cord and call-bell, substantially asspecified, in connection with a dumb-waiter, and for the purpose setforth.

3. The combination and arrangement, in a dumb-waiter, of the way D,tilting table or door F, cord G, and bell a, substantially as and forthe purposes specified.
